An object is projected horizontally at 8.0 m/s from the top of a 122.5 m cliff. how far from the base of the cliff will the object strike the ground?

Refer to the diagram shown below.

Assume g = 9.8 m/s² and neglect air resistance.
All quantities are measured as positive upward.

The vertical launch velocity is u = 0.
Let t = the time of flight.

Use the formula s = ut + (1/2)at²
Then
(-122.5 m) = 0 + (1/2)*(-9.8 m/s²)*(t s)²
t² = 122.5/4.9 = 25
t = 5 s

The horizontal distance traveled is
d = (8.0 m/s)*(5 s) = 40 m

40 m

the simple machine has three main features. they are:

loadfulcrumeffort

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
